GNSS Testing

With demonstrated experience in the field of GNSS testing, Rohde & Schwarz provides accurate, flexible, high-performance test solutions to cover every need – from design, development and production to high-end complex constellation simulation.

A number of standard tests are available for characterizing the performance of a GNSS receiver, e.g. time to first fix (TTFF) and location accuracy. Test runs often include an entire series of tests, each with a different scenario.

After a review of GPS signal structures and current satellite constellation status, this webinar provides a tutorial examination of how interference affects GPS signal reception. In particular, interrelations between jammer spectrum and GPS signal spectrum are explored.

Jamming has long been of concern to military users, and recently has also become a concern for civil users. This webinar first provides an overview of classic military mitigations against interference, including robust front end design, adaptive arrays, inertially aided tracking and other techniques.

Since BEIDOU receivers are not yet wide spread in the market, this MATLAB based application can be used to analyze and process BEIDOU signals. The free application enables and demonstrates remote operation of Rohde & Schwarz instruments using SCPI commands and attribute based drivers directly out of MATLAB scripts and functions

A GPS L1-frequency signal is recorded using a receiver such as an R&S TSMW or an R&S FSV. Then the I/Q data is stored via the digital I/Q interface on an R&S IQR device. Playback is realized using an R&S SMBV signal generator that is also connected to an R&S IQR via a digital I/Q…

The R&S®SMBV100A supports receiver testing under realistic conditions by offering features such as obscuration simulation and automatic multipath generation. Out of a multitude of possible test scenarios – with predefined or user-specific settings – this application note presents some examples to give an impression of the instrument’s capabilities
